The aim of this study was to investigate in vivo 3D cervical motion characteristics of patients who had undergone AOSF surgeries.
AOSF surgery is a classic surgical method for the treatment of odontoid fracture, but there are few studies that investigated its effect on in vivo biomechanics of the cervical spine. Postoperative biomechanical characters of the atlantoaxial joint (C1-C2) and the caudal adjacent segment (C2-C3) have yet to be clarified.
The study involved 14 patients subjected to a procedure of AOSF with lag screw. Subjects were matched with 14 healthy controls. All subjects underwent CBCT scanning of the cervical spine under seven functional positions. A 3D-3D registration was performed for each vertebra at each functional position to calculatal segment and caudal adjacent segment. Longer-term follow-up studies of larger patient cohorts are necessary to evaluate the clinical outcomes of patients after the AOSF surgery.Level of Evidence 3.
Although AOSF surgery reduced the flexion-extension ROMs of all investigated spinal segments, additionally, it reduced twisting ROMs of C1-C2 and C1-C7, but only lateral bending ROM of C2-C3, when compared with the control group. The data implied that the AOSF surgery would result in different biomechanics changes in the atlantoaxial segment and caudal adjacent segment. Longer-term follow-up studies of larger patient cohorts are necessary to evaluate the clinical outcomes of patients after the AOSF surgery.Level of Evidence 3.Retrospective.
The purpose of this study is to evaluate the effect of posterior cervical fusion lowest instrumented vertebra (PCF LIV) selection on incidence of mechanical failure, revision surgery, and patient-reported outcomes (PROs).
Recent studies indicate that the LIV in PCF may contribute to the risk of mechanical failure. To date, the evidence available to guide spine surgeons in the selection of PCF LIV remains limited.
All patients undergoing PCF at a single institution were prospectively entered into a spine registry which was retrospectively queried. Data collection included demographics, pathology, operative variables, construct LIV, outcomes of mechanical failure, revision surgery, and patient-reported disability, pain, and quality of life.
Of 438 patients undergoing PCF from 2006 to 2019, 106 patients had an LIV of C7, T1, or T2, a minimum of 1-year follow-up, and met all study inclusion criteria. LIV cohorts were C7 LIV (36), T1 LIV (42), and T2 LIV (28). There were no between-group dy a significant role in the development of mechanical complications and need for revision surgery. T2 LIV selection demonstrated a significantly lower rate of mechanical failure and revision surgery. https://www.selleckchem.com/products/LBH-589.html Postoperative PROs up to 36 months are needed to evaluate effect of LIV selection on PROs.Level of Evidence 3.A retrospective multicenter cohort study.
The aim of this study was to identify the incidence and risk factors for UPROR within minimum 2-year follow-up in primary definitive fusion for pediatric spinal deformity.
Several previous reports have elucidated the incidence of complications after pediatric scoliosis surgery; however, there has been no study that described the incidence and risk factors for unplanned return to the operating room (UPROR) with long-term follow-up in surgery for pediatric scoliosis with every etiology.
We retrospectively extracted data of patients aged &lt;19 years, from 14 institutes in Japan, who underwent primary definitive fusion surgery for spinal deformity between January 1, 2015 and December 31, 2017. The primary outcomes were the incidence of UPROR within the minimum 2-year follow-up period for any reason. Univariate and multivariate logistical analyses were conducted to identify potential risk factors associated with UPROR.
We identified 1417 eligible patients (287 m study identified for the first time the incidence and risk factors for UPROR with minimum 2-year follow-up after primary definitive fusion surgery for pediatric spinal deformity with every etiology.Level of Evidence 3.Retrospective questionnaire study of all patients seen via telemedicine during the COVID-19 pandemic at a large academic institution.
This aim of this study was to compare patient satisfaction of telemedicine clinic to in-person visits; to evaluate the preference for telemedicine to in-person visits; to assess patients' willingness to proceed with major surgery and/or a minor procedure based on a telemedicine visit alone.
One study showed promising utility of mobile health applications for spine patients. No studies have investigated telemedicine in the evaluation and management of spine patients.
An 11-part questionnaire was developed to assess the attitudes toward telemedicine for all patients seen within a 7-week period during the COVID-19 crisis. Patients were called by phone to participate in the survey. χ2 and the Wilcoxon Rank-Sum Test were performed to determine significance.
Ninety-five percent were "satisfied" or "very satisfied" with their telemedicine visit, with 62% stating it was "the al evaluation for spine surgery candidates.Level of Evidence 3.
Telemedicine can increase access to specialty care for patients with prolonged travel time to in-person visits and decrease the socioeconomic burden for both patients and hospital systems. The high satisfaction with telemedicine and willingness to proceed with surgery suggest that remote visits may be useful for both routine management and initial surgical evaluation for spine surgery candidates.Level of Evidence 3.A retrospective study.
The aim of this study was to investigate the incidence and risk factors for distal adding-on (AO) phenomenon after posterior spinal fusion (PSF) in scoliosis secondary to Chiari malformation type I (CMS) patients with right major thoracic curve.
Distal AO phenomenon is a common complication observed in adolescent idiopathic scoliosis (AIS), which is significantly associated with unsatisfactory outcomes. However, few studies specifically focused on the incidence and risk factors of distal AO in CMS.
Seventy-eight CMS adolescents were included with a minimum of 2-year follow-up after PSF. patients with distal AO at the final follow-up were divided into AO group and those without were No-AO group. The coronal and sagittal parameters were evaluated preoperatively, immediately after surgery, and at the last follow-up. Clinical outcome was analyzed using the Chicago Chiari Outcome Scale (CCOS).
Distal AO was observed in 18 of 78 patients (23.1%). Compared with No-AO group, patients with distal AO had significantly lower Risser sign (P?=?0.
